摘要：

We have investigated phonon properties of some beta-FeSi2 crystals with characteristic light emission properties by using measurements of far-infrared absorption and photoluminescence in order to discuss a correlation between them. It has been found that there is a systematic correlation between phonon states and light emission efficiency and that the phonons above the energy of more than similar to 44 meV may be effectively coupled to the optical indirect transition for the IR light emission from beta-FeSi2 crystals.
